A vulnerability, which was classified as critical, was found in HDF5 1.14.6. Affected is the function H5SM_delete of the file H5SM.c of the component h5 File Handler. The manipulation leads to heap-based buffer overflow. It is possible to launch the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product writes data past the end, or before the beginning, of the intended buffer.
